This belongs to a friend. When i got there it would not start. There are 3 vertical led’s, the top 2 were continualy flashing, i think from memory they were labelled “cooling” and “heating”. I managed to re-set it and it started working with heat. After i left, as i suspected it stopped again with the same lights flashing. Is this a fault code? What should i be looking for when i go back, sensors?
